Nadia is a stockbroker. She earns 4% commission when she sells stocks. Last week, she earned $288 in commission.

Tresset [83]

Answer:

a)The total amount of her weekly stock sales = $7,200

b) The total amount of her yearly stock sales = $350,000

Step-by-step explanation:

(a) Let us assume that the total a mount of her sales in a week = $m

Commission earned in a week = $288

Now, 4 % of her total sales = $288

or, 4% of ($m) = $288

⇒ $\frac{4}{100} \times m = 288$

or, $m = \frac{288 \times 100}{4} = 7,200$

⇒ m = $7,200

Hence, the total amount of her weekly stock sales = $7,200

b) Let us assume that the total amount of her sales in a year = $k

The total amount of commission earned = $14,000

Now, 4 % of her total sales = $14,000

or, 4% of ($k) = $14,000

⇒ $\frac{4}{100} \times k = 14,000$

or, $k = \frac{14,000 \times 100}{4} = 350,000$

⇒ k = $350,000

Hence, the total amount of her yearly stock sales = $350,000
